Host file

[Wolf]

So we were playing around in the office today, and I got into some guys computer and went into his host file and made it so if he tried to go to yahoo, he would go to google, and vice versa. Really simple, playful stuff. I couldn't help but think that since we are on the same network I should be able to do this remotely from my computer. Ideas?

host file is not remote as as I know. Perhaps you could set it up to be but. You could do this by using a local(or remote for that matter) DNS server set up as you want it to be. Or look into DNS cache poisoning.

What comes to mind now anyway.

Well... you can use simple file sharing and share the windows folder, or just the /etc/ (?) folder.
The host file is for local use, and practically for me it's useless, because it doesn't work for me (don't know why...). But anyway, write a host-file modifying malware remotely and have fun
If it's the same LAN in an office, PC's probably won't be uber secure. In that case you can exploit such human error and use a netcat backdoor, which is completely legit - if Windows firewall is in use, you might have to open the ports in there for it to work...

Thank you gentlemen, I managed to gain access through the share drive, and now have several confused coworkers.
